EXPANDING BRACELET, BELT, OR THE LIKE.

Application filed August 9, 1921.

RISON, a subject of the King of Great Britain and Irelano, residing at 7 Northampton Square, London, E, C. 1, England, have invented new and useful Improved Construction of Expanding Bracelet, llelt, or the like, of which the following is a specification.

This invention relates to the class of expanding bracelet, belt o" the like in which each unit comprises two superimposed cases carrying springs and two pairs of side plates or frames positioned outside the superimposed cases and having cross pins positioned within the superimposed cases and adapted to compress the springs in their respective cases in opposite directions, the remote ends of the respective side plates or frames being connected to the corresponding side plates of the next link by connecting links.

My present invention consists in constructing such class or" spring controlled expanding bracelet, belt or the like wherein each expanding link slides within the outer edge of the main link or case and is retained and guided by turned over edges thereof, the upper sliding link of each expansible unit being connected to the lower link of the next expansible unit.

My invention will be clearly understood from the following description aided by the accompanying; drawings in which Figure 1 is a side sectional elevation, Figure 2 a longitudinal section on the line 2-2 of Figure 1 and Figure 3 a section on theline 3-3 of Figure 1, of a spring link constructed according to my invention the attachment at the ends being shown for connectionto another link and for connection to a watch.

Figure el-is a side elevation of a top sliding link and showing the means at the end for connection to thenext link.

Figure 5 is a side elevation oi a bottom sliding link for connection-to a watch.

Figure 6 is a side elevation of a top link provided with means "for connection to a top slidinglink of the next link the two links being positioned at the centre of the bracelet.

.Figure 7 is a plan of a sliding link for use with very wide bracelets and in which it is advisable to use two springs for each sliding link. I

Serial No. 490,957.

Figure 8 is a plan of a bracelet slightly opened out.

Figure 9 is a side elevation of a bracelet.

Figs. 10 and 11 are opposite end views respectively of the main link.

1 construct each ordinary link A with open sides and closed ends and within such link A 1 position centrally a wall B running from end to end and across from one side to the other such wall being securely held to the ordinary link.

Each sliding link C, D consists of two bars connected at their ends. To one end of each top sliding link C except the two central. sliding links hereafter described I fix a hinge joint F, this joint preferably consisting of a piece of metal in the form of: the figure 8 in section. the upper halt of this hinge joint being soldered to the link C shown at Figure 4E.

The bottom links D are constructed the same as the top links C but without the fasening device except the two end bottom links which are provided with upturned lips F between which is-pivoted a fastening device G in theform oi the 8 tor attachment of a watch but any other form of fastening device may be attached to the ends of the end bottom links.

Each of the top and bottom links C. D, is positioned within the ordinal link-A, one above, and the other below, the wall B thereof, their respective opposite ends extending beyond the ends of the link A, as shown. Figure 1. In order to allow the outer edges of the bars, forming the sides of the links C and D. to lie substantially flush with the outer side edges of the link A.,the latter is formed with two recesses in its width, at one end, in which the sides of link C are housed and are adapted to slide. and with two similar recesses at its other end in which the sides of link D are housed are adapted. to slide. To further secure the links 0, D in the link A and prevent any side movement l turn over or form a bezel ll along the inside edges of links A to hold the links (l, D within the link A.

Within each link C, D l position a spring l which has a bearing against one end of the link A and against one end of the link C or D.

With regard to the two central links A (see Figures 6, 8 and 9) I form the top slide ing links'C plain and connect them together by a ring J and to enable a proper working of the bracelet the top sliding links C on each side of the centre links A A are arranged so that the hinge joint E is positioned atthe end farthest from the centre links A A The sliding links D are connected to the hinge joint 15 somewhat loosely so that the bracelet can be folded or curved inwardly to allow the bracelet to be manipulated.

For extra wide bracelets the sliding links C, D may be made with divisionstrips K of any desired number with a spring 1-positioned-between each as will beunderstood from Figure 7 .By this invention I can obtain an expansion of. about three quarters of the length of the bracelet or belt a feature not attainable b other similar constructions of brace-v said housings, a spring located between oneend of-said lower housing and one end of said lower link, in combination with connecting links adapted to connect the upper link of one unit with the lower link of an adjacent unit, for the purposes set forth.

2. A spring controlled expanding bracelet, beltor the like, comprising a series of units eachof said units consisting of a. main link formed of strips connected together at their ends and open along their sides, a division wall disposed longitudinally between said strips and forming two housings for separate springs, an upper sliding link extending through one of said housings at one end, a spring located in said upper housing and hearing at one end against one end of said upper housing and at the opposite end against the end ofthe upper sliding link extending through said housing, a lower sliding link extending through the other or said housings at one end, a spring located in said lower housing and adapted to hear at one end agalnst one end of said lower housing and at the opposite end against the end of the lower sliding *link passing through said lower housing, and connecting links between the upper sliding link of one unit and the lower sliding link of an adjacent unit, for the purposes settorth.

3." A spring controlled expandingbracelet,
